Application September 2, 1955, Serial No. 532,231

2 Claims. (Cl. 219-45) This invention relates to an improved non-foggingmirror, the primary object of the invention being to provide a heatedmirror structure of this kind which is adopted to be used either as anattachment for an existing bathroom mirror or as a mirror door to beincorporated in a medicine cabinet during manufacture of the cabinet.

Others objects of the invention will appear from the followingdescription, the claims appended thereto, and from the annexed drawing,in which like reference characters designate like parts throughout theseveral views, and wherein:

Figure 1 is a perspective view;

Figure 2 is a vertical longitudinal section on line 2-2 of Figure 3;

Figure 3 is a transverse vertical section on line 3--3 of Figure 2;

Figure 4 is a top plan view;

Figure 5 is a horizontal section on line 5 5 of Figure 2; and

Figure 6 is a diagram of the wiring of the device.

Referring in detail to the drawings, the illustrated mirror structurecomprises a rectangular flat casing 8 of shallow depth, including arectangular frame 10 formed of thin wood (though other materials may beused) having an inwardly projecting retaining flange 12 around its frontedge to hold in place a mirror panel 14 the back of which is engaged bya retaining strip 16 on the frame 10 and spaced rearwardly from theflange 12. Closing the rear of the casing is a back plate 17 of aluminumor other suitable material.

Means to heat the interior of the casing 8 includes an upstandingelectrical lamp bulb socket 18 mounted on the bottom wall 17 of theframe 10. A bulb 20 is engaged in the socket. Extending from the socketare conductors in one of which is interposed a manually operable switch22 mounted on the side wall 19 of the frame with its handle projectingexteriorly of the casing. The conductors are encased in an electricconvenience cord 24 extending through a grommet 26 mounted in the sidewall 19 of the housing near the upper end thereof. A connector plug 28on the outer end of the cord can be plugged into a convenient currentoutlet.

In place of a light bulb, any suitable heat-producing means may be used,such as a resistance element, and the location of the heating meanswithin the casing may be varied as desired, as long as said meansserves, when energized, to raise the temperature of the outer surface ofthe mirror panel 14 above that at which vapor will condense thereon.

The dissembled device is designed to be suspended from the upper edge ofan existing bathroom mirror,

ice

2 in overlying relation to the front surface of the mirror. Accordingly,secured to the top wall 21 of the frame 10 are oppositely butidentically formed brackets 30, 32 each formed from a single piece ofmaterial, and another pair of brackets 34, 36 also formed each from asingle piece of material.

Brackets 30, 32 have upwardly oifset horizontal portions 31 and 33projecting in opposite directions, toward the respective sides of theframe 10, and the cord 24, as shown in Figure 2, may be wound about thevertical portions 35 and 37, when not in use, as shown in dotted linesin Figure 2.

The horizontal portions 39 and 41 of the brackets 34 and 36 underlie thehorizontal portions 31 and 33 of the brackets 30, 32, and the brackets34 and 36 have downwardly projecting portions 38 and 40 which are spacedfrom the back of the frame 1t), adapted to hook over the top edge of abathroom mirror, a medicine cabinet door, or the like.

The invention, it will be understood, can be embodied in a medicinecabinet during manufacture thereof, if desired. ln these circumstances,the casing 8 would be the door of the cabinet, devoid of the suspensionmeans 34, 36, and would be only slightly thicker than doors not having aheating means incorporated therein.

It is believed apparent that the invention is not necessarily confinedto the specific use or uses thereof described above, since it may beutilized for any purpose to which it may be suited. Nor is the inventionto be necessarily limited to the specific construction illustrated anddescribed, since such construction is only intended to be illustrativeof the principles, it being considered that the invention comprehendsany minor change in construction that may be permitted within the scopeof the appended claims.

What is claimed is:

1. In a non-fogging mirror structure, a casing comprising a frame havingtop, bottom, and side walls, said walls having front edges and rearedges, a mirror panel secured in said frame at the front edges of saidwalls and spaced forwardly from said rear edges, a back plate secured tosaid rear edges, an electrical heating element within the casing andmounted on one of said walls, rearwardly projecting brackets on said topwall terminating in downwardly projecting portions spaced rearwardlyfrom said back plate, and a cabinet door having an upper edge and frontand rear faces, said brackets being engaged with the upper edge of thecabinet door with said downwardly projecting portions engaging the rearface of the door and with said casing engaging the front face of thedoor.

2. The structure according to claim 1 which includes in addition anelectric cord leading 'from said heating element and traversing a sidewall of the frame and wound around said brackets projecting exteriorlyfrom said frame top wall.
